Slide3Understanding Flu
Influenza (flu) is a contagious respiratory illness
Caused by influenza viruses
Spread by tiny droplets made while coughing, sneezing, or talking or by touching surfaces that have flu virus on them
About 8% of U.S. gets sick from flu annuallyInfluenza virus particles (digitally colorized transmission electron microscopic image)
Slide4Think About It
How can a disease cause a pandemic?
What groups of people do you think need to be concerned about pandemic flu?
If you were the U.S. president, what would you do to prepare for pandemic flu?
Slide5Pandemic Flu and CDC
Seasonal flu occurs annually; pandemic flu only occurs when a novel (new) flu virus infects many people and spread to a wide areaFlu pandemics since 1900:1918 H1N1 pandemic flu, ~50 million casualties1957 H2N2 pandemic flu, ~1.1 million casualties
1968 H3N2 pandemic flu, ~1 million casualties2009 H1N1 pandemic flu, ~284,000 casualties

Slide6Pandemic Flu and CDC
The World Health Organization (WHO) estimates that preparing for a pandemic costs less than 1% the cost of responding to oneHomeland Security Council in 2005 developed the National Strategy for Pandemic Influenza to guide pandemic preparationsFocus areas:Gathering timely flu data
Using nonmedical measures to stop fluUsing medical measures to stop fluProviding training and equipment to health systemsImproving communication strategiesExpanding research and lab facilitiesPlanning with international partners
Slide7Think About It
The World Health Organization monitors which influenza viruses are currently circulating to make vaccines that protect against those specific viruses. Sometimes the vaccines are not a good match to the outbreaks. What do you think that means for the immunity of the population? How will it affect cases and deaths?
In recent pandemics, the World Health Organization has opted for more generic names for diseases and infectious agents rather than the typical place-based options. Rather than calling it Spanish flu, 1918 pandemic flu is generally used. Why is this change important from a social equality perspective?
How has our experience with pandemic flu helped us to prepare for the COVID-19 pandemic?

Slide9Think About It
What are some other
pandemics
that occurred before the 1900’s that you’ve learned about in the past? How did they change history?
Should epidemiologists consider anything other than direct health effects when responding to pandemics? For instance, if a quarantine due to disease exposure is going to cause someone to lose their job or house, should that be considered?The response to COVID-19 in the United States was slow at first, due to political divisions. Do you think that pandemics are always inherently political? Why or why not?
